Product Profile:

The frequency and voltage regulation static power supply developed by our company takes the DSP processor as the core, adopts SPWM control technology and DDS direct digital waveform synthesis technology, combines power electronics technology, automatic control theory, digital signal processing technology and information technology, realizes the intellectualization, digitalization, visualization and programmability of the frequency and voltage regulation power supply, and the product is in the leading technology in China.

Functional characteristics:

1. Programmable Functions

A. General function - set a set of voltage, frequency, time, operation output;

B. Step function - --- Setting up multi-group (up to 30 groups) step voltage, frequency and time, according to the set step output, the number of cycles and cycle interval can be set;

C. Gradient function - --- Setting the starting voltage frequency, terminating voltage frequency, starting time and running time of multiple groups (up to 30 groups), the system automatically changes the VF output according to the setting.

D. VF Start Kinetic Energy - For motor testing and high-power motor start-up, the mode of variable frequency and voltage after constant frequency and variable voltage can be set to reduce the impact current at start-up.

E. Special curve imitation - --- For complex voltage and frequency changes, according to customer requirements or related test labeling, see voltage and frequency curve become solidified in the system.

2. Parallel Redundancy Function

A. It can work in parallel with two or more computers. Improve the availability of power supply;

B. Dual computer redundancy. Improve the reliability of power supply;

C. It can work independently and in parallel with two or more machines (independently: single machine can set frequency and voltage arbitrarily. When working in parallel.

3. Multipurpose Function of One Machine

A. It can work in standard three-phase output mode and output standard three-phase voltage with phase difference of 120 degrees each other.

B. It can also work in single-phase mode. At this time, the three single-phase output voltages, frequencies and phases are exactly the same. Three single-phase outputs can be directly connected in parallel outside the power supply. It can be used as a single-phase power supply, which is three times higher than the single-phase load capacity of the traditional power supply. Single-phase and three-phase function switching only needs one key switching, does not need complex internal line adjustment, and the power supply has self-diagnosis and protection functions, effectively preventing output short circuit caused by single-phase and three-phase mode wrong switching;

C.three-phase control function: three single-phase output frequency and output voltage can be independently adjusted, three single-phase can output different frequencies and voltages.

4. Three-phase phase angle adjustable function

In the three-phase output mode, the phase angle of the three-phase output voltage can be adjusted to a range of 0-360 degree and a resolution of 1 degree.

5. RS232/RS485 Communication Interface

Using MODBUS communication protocol, users can achieve centralized control by computer or PLC, set the operation command of the inverters, modify or read the functional parameters, read the working status and fault information of the inverters, etc.
